I don't disagree but the reason schools are turning to alternatives is because schools can't afford the labor to do those things.
Hall monitors did this for generations.
The majority of US schools report struggling to hire paraprofessionals.

> That would be the labor I'm referring to.
The generations of hall monitors were students. They're free.
Do you really think other students are best equipped to deal with students having sex, doing drugs, or devious licks in the bathrooms?
And in any case, the hall monitors are probably better off in class instead of being unpaid labor.
